Ruth Mary Rogan Benerito (January 12, 1916 – October 5, 2013) was an American physical chemist and inventor known for her huge impact work related to the
.Personal life
Ruth Mary Rogan Benerito was born and raised in New Orleans in 1916.[1] Her father, John Edward Rogan, was a civil engineer and railroad official and was described by his daughter as a pioneer in women's liberation movement. Her mother, Bernadette Elizardi Rogan, was an artist and considered a "truly liberated woman" by her daughter.[2] Both parents were college graduates and imposed their values regarding a strong sense of education and women's rights onto Ruth.
The Great Depression era surrounded Ruth Benerito's early years and when she eventually received her B.S. in chemistry, one in five Americans was unemployed.[3] Benerito's original interest preceding chemistry was math; however, she did not want to foster a career as an actuary simply estimating probabilities for insurance companies, which led her to study chemistry.
Benerito got married to Frank Penchot Benerito, who had served in World War II. Frank worked in the car business and fully supported his wife's research and hard work.[4]
Later in her life as she reflected on her many achievements, the true essence of her character was illustrated when she said, "I believe that whatever success that I have attained is the result of many efforts of many people. My very personal success was built from the help and sacrifices of members of my family, and professional accomplishments resulted from the efforts of early teachers and the cooperativeness of colleagues too many to enumerate."[3]
Education
In an age when girls did not usually go on to
She then moved to Newcomb, where she taught chemistry while researching advanced quantitative analysis and physical chemistry, organic chemistry, kinetics, and thermodynamics. While working as a teacher, Benerito took night classes to earn her master's degree from Tulane University. In 1948 she received her doctorate degree from the University of Chicago, where she conducted physical chemical research under the direction of Thomas F. Young. Her Ph.D dissertation was titled "Activity Coefficients of HCl in Ternary Aqueous Solutions". She left her job as an assistant professor in Newcomb College in 1953 to work at the USDA Southern Regional Research Center of the US Department of Agriculture in New Orleans, where she spent most of her career.[5]
At the USDA she worked in the Intravenous Fat Program of the OilSeed Laboratory, and in 1955 she was promoted to project leader. In 1958 she was promoted to acting head of the Colloid Cotton Chemical Laboratory, and in 1959 she became the research leader of the Physical Chemistry Research Group of the Cotton Reaction Laboratory. Benerito completed a
She retired from the USDA in 1986 but continued to teach part-time at Tulane and the University of New Orleans.[6][7]
Contribution
Invention of wrinkle-free cotton
Benerito is most famous for her work relating to the use of mono-basic acid chlorides in the production of cotton, with which she had 55 patents. She invented these wash-and-wear cotton fabrics, which allow for more wrinkle-free and durable clothing, while working at the
While she is publicly credited for the invention of wrinkle-free fiber, she did not believe she singlehandedly invented it. She clarified her role in a 2004 USDA interview by stating, "I don't l ike it to be said that I invented wash-wear because there were any number of people worked on it and the various processes by which you give cotton those properties. No one person discovered it or is responsible for it, but I contributed to a new process of doing it."[3]
The secret of the invention is the use of a process known as
It was first thought that crosslinking was making the cotton fabric wrinkle resistant by strengthening its fibers, but the amount of crosslinking used in Benerito's treatment is small and does not add much strength. She developed a new theory on how crosslinking works. It is known that cellulose molecules can stick to each other by means of the weak
Laboratory equipment
Benerito's research led to the development of glassy fibers that proved useful in the manufacture of laboratory equipment.[13][14]
Method of feeding seriously wounded soldiers
Besides her contribution to the textile industry, during the Korean War, Benerito developed a way to give fat intravenously to patients who were too sick to eat—a method used to feed seriously wounded soldiers.[15] The experiment looked into the proteins and fats in seeds like peanuts, almonds, and pistachios. The goal was to find a way to feed these fats directly into the patient's veins to provide them high-calorie nutrition for their physical activities. This method saved many lives.[16][17]
